Practical investigation of aircraft pressure cabin MSD and corrosion

Longitudinal lap splices from several types of transport aircraft pressure cabins were investigated for Multiple Site Damage (MSD) fatigue and corrosion. The lap splices came from five service aircraft, three Fokker F28s, a British Aerospace BAC 1-11 and a Boeing B727-100; and a fullscale test on a Fokker F100. The results are compared with NASA...

Fatigue and corrosion in aircraft pressure cabin lap splices

Aircraft structures are susceptible to fatigue and corrosion damage, notably at joints. There may be interactions between fatigue and corrosion, especially as aircraft age. Longitudinal lap splices from several types of transport aircraft pressure cabins were disassembled and investigated for Multiple Site Damage (MSD) fatigue cracking and...
